Gamma 4415N

Gamma(10A~40A) series is advanced maximum power point tracking (MPPT) charge controllers for off-grid photovoltaic systems, with optional display units. It is designed according to the international standard with higher quality, reliability , and safety. The limitation function of the charging power, charging current, and automatic power reduction function fully ensure stability when working with oversize PV modules(max.1.5 times of rated power) and operating under a high-temperature environment.

  • MPPT tracking efficiency above 99.5%
  • Maximum charge conversion efficiency as high as 97.4%
  • Support lead-acid and lithium-ion batteries
  • Multiple load work modes
  • Charging power and current limitation function
  • High-temperature charging power derating function
  • Standard Modbus communication protocol with isolated RS485 interface
